During this study the formation and growth of silver chloride crystals in crazed porous polymeric matrixes of poly(ethylene terephthalate) (PET) and polypropylene (PP) were under investigation. The rate of formation and dispersity and the way AgCl particles aggregate in porous polymers were shown to be dependent on the effective volume porosity, pore dimension, and physical state of the polymer. Methods of the determination of diffusion and distribution constants for low-molecular substances in porous polymers were suggested, and a mechanism of silver chloride crystallization in porous medium was proposed.

The current surface-enhanced Raman scattering (SERS) substrates typically feature a single energy level, posing challenges in coordinating electromagnetic enhancement (EM) and chemical enhancement (CM), thereby limiting the sensitive detection of numerous crucial target molecules. In this study, novel aggregated nanorings (a-NRs) hybridizing Ag, Au and AgCl are constructed as SERS substrates. On one hand, the obtained a-NRs exhibit robust localized surface plasmon resonance absorption, whose wavelength can be tuned to match three commonly used laser wavelengths (532, 633 and 785 nm) to gain strong EM effect.

For the first time, Ag/AgCl/zeolitic imidazolate framework-11 nanocomposite (Ag/AgCl/ZIF-11) as photocatalyst was synthesized and investigated on tetracycline (TC) degradation under visible light. ZIF-11 (Z), Ag/AgCl (A), and four composites (AZ, AZ, AZ, AZ) were made and characterized by XRD, FTIR, Raman, BET, SEM, EDS, XPS, and DRS analysis. The characteristic peaks of ZIF-11 and Ag were observed at 4.

This study proposed a microfluidic chip for the detection and quantification of NSE proteins, aimed at developing a rapid point-of-care testing system for early lung cancer diagnosis. The proposed chip structure integrated an electrochemical biosensor within a straight PDMS microchannel, enabling a significant reduction in sample volume. Additionally, a method was developed to deposit silver and silver chloride layers onto the reference electrode.
